Warning: Ensure all wiring is correct and secure before restoring power. Incorrect wiring can lead to damage to the meter, electrical hazards, or inaccurate readings.
6. Operation
6.1 Power On
Once properly installed and wired, restore power to the circuit. The LCD display will illuminate, and the meter will begin measuring energy consumption.
6.2 LCD Display
The LCD displays the cumulative active energy consumption in kilowatt-hours (kWh). The reading will increment as energy is consumed.
6.3 Indicator Lights
- A, B, C (Green LEDs): Indicate the presence of voltage for each phase. They should be steadily lit when power is supplied to the respective phase.
- REV (Red LED): Illuminates if reverse current flow is detected. This indicates incorrect wiring or an issue with the load.
- PULSE (Green LED): Flashes to indicate active energy consumption. The flash rate is proportional to the power being consumed (400 imp/kWh).
7. Maintenance
The DDS578C energy meter requires minimal maintenance. Regular inspection is recommended to ensure optimal performance.
- Cleaning: Gently wipe the meter's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check all wiring connections for tightness and signs of wear or damage. Ensure the meter is securely mounted.
- Environmental Conditions: Verify that the operating environment remains within the specified temperature and humidity ranges.
Caution: Do not attempt to open or repair the meter. Refer all servicing to qualified personnel.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| LCD display is blank | No power supply; Faulty wiring | Check power supply to the meter. Verify all wiring connections are correct and secure. |
| Phase indicator (A, B, or C) is off | No voltage on that phase; Loose connection | Check the voltage supply for the affected phase. Inspect wiring connections for that phase. |
| REV indicator is lit | Reverse current detected | Review wiring for correct phase and neutral connections. Ensure current transformers (if used) are installed with correct polarity. |
| PULSE LED not flashing | No load connected; Meter malfunction | Ensure there is an active load consuming power. If load is present and other indicators are normal, contact support. |
| Inaccurate readings | Incorrect wiring; External interference | Double-check all wiring against the diagram. Ensure the meter is not exposed to strong electromagnetic fields. |
